You have to remember that we buy a lot of goods from Europe, I don't see that VW, BMW or Mercedes will not want to sell to the UK, our trade with Europe will be unaffected as Europe has too much to loose. Switzerland does OK out of the EU.....

Well of course they will be happy to sell to you! But you've got a trade deficit with the rest of the EU and it is widening, so clearly they are already not too excited about buying from you, of course if the pound was to fall as 20% or 30% after an exit that might change.
